GOVERNOR.

Application filed May 6, 19242. Serial No. 559,100.

(GRANTED 'UNDER THE ACT OF MARCH 3, 1883; 22 STAT. I.. 625.)

The invention described herein may be used by Vthe Government, or .anyof its oiiicers or employees in prosecution of work 'for the Government,or by any other person in the United States, without payment of anyroyalty thereon.

This invention relates to governors, and more particularly to a formespecially adopted 'for use in combination with a well known :torm ofmagneto, whereby the spark, for instance, in the combustion chamber oi'an internal combustion engine, may be. discontinued when the speed ofrotation has reached a predetermined rate. j p

The objects are to provide a simple, durable and inexpensive device thatmay be applied to a magneto by simply adding the t'ew parts required,and only slightly changing one of the parts of the magneto as originallyplaced on the market. f

A Ifurther object is to provide la device of a character that may besold as an attachment for a magneto and may be applied by one that isnot necessarily an expert me* chanic.

A further, object being to break the high tension current just prior toits discharge from ythe distributorat the end of the vmagneto by openinga gapl between the end of the high tension pencil and the contact platein the rotor of the distributor, when the motor to which the vmagneto isattached, has passed a predetermined R. P. M.; said structure alsoproviding for the automatic reestablishment of the current through ltheparts when the engine has resumed its predetermined maximum R. P. M.

For purposes of illustration, one form of this device is shown, it beingunderstood that minor detail changes in construction may be resorted towithout departing from the spirit of the invention.

Similar numerals indicate corresponding parts in all the ligure-s of thedrawings in which: p

Fig. l is a vertical section of my improved governor, showing adjoiningfragmentary parts of a well known magneto, as at present placed on themarket.

Fig. 2 is a detailed perspective View of the governor body, or spider.

,Fig 3 is a similar view of the governor slide sleeve.

Fig. 4 is a similar view of the distributor rotor.

Fig. 5 is a similar view of the governor arms, links, ily balls andsprings, assembled.

Fig. 6 is a similar view of the magneto pencil.

Reference now being had to the drawings by numerals, l indicates a wellknown Jform of magneto, 2 the high tension brush holder, 3 indicates onemember ot the safety spark gap, connected by tleXible arm 4, with thebrush holder 2.

The usual distributor rotor magneto gear 5, and its driving pinion 6,are shown in Fig. l. Ordinarily the distributor block 7, with itsinsulating ring 8,V is mounted directly on the magneto 1, and thedistributor .rotor 9 is mounted directly on the gear 5.

When this improved governor is applied, the above named parts are in noway altered as to their structure, but are simply detached from theparts mentioned and a governor housing, or tubular extension l0, isinserted between the magneto casing 1 and its dis,-

tributor block 7, and a governor body or spider ll, is inserted betweenthe gear 5 and the distributor rotor .9. All mounting and securing meanscorresponding, and are interchangeable.

To mount what is known as the high tension pencil in the form of magnetoshown, it has always been necessary to insert the outer point of thepencil into the distributor rotor and telescope a sleeve against thetension ot a spring at the other end o'll the pencil in order to adjustthe biiurcatedinner end of the pencil on the high tension brush holder2.

Said pencil 12 is in no way altered as to structure, but is simplylengthened to reach its seat in the rotor 9 in its adjusted or outerposition. By reference to F ig. l, it will be seen that the pencil isprovided with the reduced inner end 13, adopted to form an abutment forone end o1c a coil spring lll, located in a telescoping sleeve l5, saidsleeve being provided with the usual biturcated end 1G,

`adopted in its usual way to straddle the shank or terminal of the hightension brush holder.

The pencil may be of insulating material and conductor 17 may extendthrough same and come into contact with the distributor Contact plate18, which, in turn, transfers lOl) the electrical energy to thedistributor contact brushes i9, and trom these out through cables (notshown) secured by the terminal nuts all in the usual manner.

By reference to Figs. l and :2, the governor body or spider ll, consistsof end plates 2O and 2l, connected by parallel members 22. rl`he plates20 and 2l are provided with central openings through which the pencilentends. Plate 2O is provided with ears 2a, between which governor armsvll, are pivotally mounted on pins 25, said plate 2O being'lperimtne-ntly secured by screws 26 to the gear 5 ot the magneto.

'.lo' the outer plate 2l, is secured by screws 2i', the magneto rotor 9.

A governor slide sleeve 2S is mounted for longitudinal movement on theaxis of rotation in a central chamber 29, in the rotor. Said sleeve 28being provided with ears 30, between which one end oi the governor armlinks 3l are mounted on pins 32. The opposite ends ot' links 3l aremounted on pins 33, in ears 34 mounted on or forming an integral part ofthe governor arms.

Any preferred 'form of tension springs 35 may be mounted on the governorarms such as shown, and maybe secured at their ends in aperturedprojecting ends ot. bearing pins 33, and tend to retract the governorarms.

F ly balls 36 are shown adjustablyv mounted on screw threaded extensions37', of the governor arms.l and may be secured in their adjustedpositions on said arms by lock nuts 38. y

By adjusting the fly balls V36 away from the aXis ot rotation of thegovernor, the i'naximum or operating R. P. M. will be reduced. y y

The high tension pencil l2 is provided with shoulder 39, immediatelyadjacent to the inner end of the sleeve 28, against which the sleevecomes into contactV when the governor operates.

In the use of this device, a positive check is obtained against racingthe engine, the ily balls are adjusted and locked in the position tooperate at a maximum predetermined R. P. lift. lVhen said speedisreached, the ily balls are thrown out against the tension of springs 35,arms 4:0 swing out, carrying with them the inner ends ot' links 3l, theouter ends being secured to sleeve 28 will cause same to be partiallywithdrawn' trom the chamber 29 in the rotor, causing said sleeve to comeinto contact with shoulder 39 ot the pencil and move same back againstthe tension of compression spring 14E, withdrawing the outer end il ofpencil l2 out ot engagement'v with the distributor plate 18, therebyinterrupting the transfer of current through the several terminals, andthe ignition spark will be discontinuedin the' V,several cylinders'untilthe speed of the go'vernoris again reduced to its maximumv operatingspeedv7 at which time spring 35 will retract governor arms ILO, whichwill in turn slide sleeve 28 bacl; to its normal position and permit thehigh tension pencil under the pre:- sure ot spring la to return to itsnormal position and reestablish the electrical connection between themagneto and the distributor plate.
